Can't update my 9550

I have been using leaks and hybirds since my 8330. Now I can't get loader or desktop manager to find the OS installed on my computer. They both find no updates for my 9550. I have tried the last 2 leaks and 2 different computers. And yes I delete the vendor files. Please help ! Oh and I'm using desktop ver. 5.0.1 I also tried 4.3 with the same results.
